on. VAPOBIZER AND Brianna.

To all whom it may concern.

Be it known that I, HARRY PRICE, citizen of the United States.residing at Boston, in

, the countyof Suffolk and State of Massa-. J

chusetts, have invented new and useful Improvements in .Oil Vaporizers and-Burners,

. of said pipe line communicating with the body 12, and preferably with the lower end of a vertical oilconduit 17 (Fig. 4) formof which the following is a specification.

This invention relates to I apparatus for vaporizing-fuel oil and burning the vapor for heating purposes, the apparatus being.

- adapted to beusedparticularly in a stove or furnace, and' comprising anoil. vaporizing chamber or retort having a vapor burner arranged to externally heat said retort, and 15 thus vaporize the oil therein, and to supply heat forother purposes, means being provided for supplying heat to the retort.

The invention is embodied in the improved apparatus hereinafter described, having provisions for quickly vaporizing. oil,

and for burning the same, and also having provisions for preliminarily heating the chamber or retort, as in first, starting the operation of the apparatus.

Of the accompanying drawings forming a part of this specification, f

Figure 1' is a top plan view of an oil vaporizer embodying the invention, adapted for use in a cooking stove. I

Fig.2 is a section on line 22 of Fig. 1. Fig. 3'is a section on line 33 of Fig. 2. Fig. 4 is a section on line 44 of Fig. 1. Fig. 5 is an end elevation of the vaporizer shownlby the preceding figure, and a sec- ZtlOl'liLl view showing portions; ofa cooking stove in which the vaporizer is installed.

Fig. 6 is a'plan view, representing a form suitable. for insertion in the fire-box'of a furnace. r

' hollowarms 13, each being-a duplicate of the other.

l 3 Oil is delivered to the body 12 from a suiting apart of s aidbody, the upper end of said conduit communicating through an arranged to direct its flame upwardly.

20 represents a flame. deflector I located above the burner 19, and arranged to direct a portion of the flame toward the adjacent surfaces of the body 12 and arm 13, and thus externally heat the vaporizing chamber and vaporize the oil therein. Other portions of theflame are deflected in different directions by the deflector 20 to supply heat to a stove or furnace.

21 represents an elongated oil burner located under the body 12 and arm or arms13, said burner being preferably formed asan open pan,,in which oil may be burned to preliminarily heat the vaporizing chamber.

The body 12 and the arm or arms 13 of said v. chamber are preferablyprovided with substantially vertical-fines 22, adapted to conduct heated products of combustion from the burner 21 through said bodytand arm or arms, and thus facilitate the vaporization of the: oil.

. I The deflector 20-is connected by a stem 23 ,with a horizontal intercepting plate 24, supported above the vaporizing chamber, and

preferably composed of two substantially circular end portions, and a neck connecting said portions, as shown bv Fig. 1. I

I prefer to adjustably support the deflectors 20 so that they may be adjusted toward-and from'the vapor burners 19. As

{here shown,the plate 2 1 is provided with two slots 25 nd26.-. -.Qae;edg thesIQt 251 is beveled to form a tooth 27. The plate is provided at or near the other slot with a downwardly projecting dog 28. The body 12 iSePro'vided with two ra'tclist-toothed members'29 and 30, one projecting into the slot 25, and the other into the slot 26. The teeth of the member 29are adapted to, engage the slot edge 27, and, the teeth of-the member 30 are adapted to enga e the dog 28. Provision is thus made for supporting thepla-te 2 1 and deflectors at various heights above the vapor burners.

The vaporizing chamber and the -'oil burner 21 may be formed in a single casting,

as indicated by'FigI 2, andthe oil burner may restupon the grate 32 of a cook stove, as shown by Fig.5.

At' the outset, a suitable quantityof oil is poured into-the pan or oil burner 21, and ignited. When the products of combustion impinging on the exposed surface of the vaporiz'ing chamber and on the Walls of'the' fines 22 have sufiiciently heated the'chamber,

oil is admitted through the pipe line '15, and 25 is immediately vaporize'd,' and is ignited at the vapor burneror biirn'ers 19. The flame-"- from said'burners,'as already stated, externally heats 'thevaporizin'g chamber and thus continuously vaporizes the oil admitted thereto.

The body 12 is'preferably externally corrugated, as-sho'wn" by Fig. 3, the corruga-" tions extending vertically and increasing the heat-absorbing surface area of the'body.

The arm 13 is provided with a tapped 'socket' 32 engaged with the screw-threaded tubular shank 33 of the burner-19, and surmounted by a cup 34 adapted to receive any oil which may flow unconsumed from the burner before the oil is vapori'z-ed,and provided with an outlet 35 permitting oil to flow into the pan or burner 21.

The intercepting plate 24 not only sup- I ports the deflectors 20 and spreads the flame from the burners, but also collects sootresulting from imperfect combustion, at'the commencement of the operation, said plate I being, provided with a downwardlyprojectin g marginal flange 24. The plate may be- 'gaged by" a stove cover litter, so that it may provided with a socket 24 adapted-to be enbe conveniently removedjto dislodge soot, I manipulated to vary its height;

1 arms 13 connected "with the body 12 by Fig. 6 represents a modification, inwhich thevaporizing chamber includes abody 12 hollow necks-13 vapor burners 1 9 anddefl'ect'or's'20 located above said burners. 'A

- s-ubsta-ntially triangular oil-burning pan 21 is located under 't'hevaporizin'g' chamber;

' Fig, 7'=shows a body 12" having an oil in- 'let 36-at its upper portion and 'alielica-l oil surrounding "the body anticoma 1% -coaeratee7 in with the pipe" the 15 {and with efiect, a corrugated heat-absorbing surface exposed to heat from the vapor burner.
